Webto orifice discharge. Simply stated, it is difficult to determine the headloss in such a system with the usual headloss (pressure loss) formulae. The usual approach is to calculate the headloss in the pipe segment between the terminal orifice (Al in Figure 1) and the next orifice (A2) based on a specified residual head and the flow WebThe equation for computing the discharge of the standard submerged rectangular orifice is: (9-1b) where: Q = discharge (ft 3 /s) C c = coefficient of contraction C vf = coefficient of … WebGenerally speaking, the headloss coefficient that is used is up to your engineering judgment. But if you are not sure of the value to use, you can use the standard headloss equation, Hl = K*V2/2g. where the "K" is the headloss coefficient. It is important to note that this is different than the "orifice coefficient" or "coefficient of discharge". order of radiation energy
